REBoUND CHECK.

Application `filed. August '25, 1924,. Serial No. 734,046.

To all whom it may con-oem.' i

Be it known that I, SAMUEL S, FALKIN- BURG, a citizen ofthe UnitedStates, and resident of Chicago, in the county of Cook and Statefot'Illinois, have invented certain new and useful Improvements in a ReboundCheck, of which the `following is a specification. n

My invention relates to improvements in rebound checks loruse onautomobiles to prevent the automobile body rising too far after it hasbeen depressed.

The object of my invention is to provide a rebound checlrot' simplecharacter; which can be readily'secured in place without the .necessityof doing any machine work upon the automobile; and which, when oncesecured in place :will not tend to be4 loosened by the strains producedby driving over rough roads. `A further object is to provide meanswhereby the length of the device can `be accurately and `quicklyadjusted.`

My invention will be more readily understood by reference to theaccon'ipanying tical sectional view on the line drawing forming and inwhich Figure l, is a fragmentary vertical Vsection of an automobileshowing a side View of a rebound check with whichit is equipped `and`which rebound check embodies my invention in a- `preferred iiorm;

Figure 2, is an enlarged fragmentary ver- 2-2 of Fig.

part of this specification l; and

` .Figure 3, is a fragmentary vertical sectional view on the line 3 3 ofFigure 2.

In said drawings 1 illustrates a channel side member of the automobilechassis frame and 2 illustrates theaxle housingwhich as usual extendstransversely of the frame Vand is spring connected to the frame in anyusual manner. The regular springs are' not shown. l

The rebound check provides a connection between the frame and the axlehousing which can yield to some extent to permit the two members toseparate somewhat but which prevents their separation to such an extentas to endanger the main load carrying springs. Y

As shown, my improved rebound check consists` of an extension spring-'3secured at its upper end tothe chassis frame, and con- Y nected at itslower end to a strap connector 4 which is adapted to pass down aroundthe axle housing 2 and having its free end erating position.

5 connected to the opposite end 6` soas to form a loop in which theaxlehousing lies.

the coils thereof lie in close Contact as shown. It is` capable of beingextended by a pull on the strap d. Y Y y For securing the spring to thechassis member 1, I :tormlthe upper end of the spring into anI ey'e?,and I provi-de a bolt 8 rPhe s rinfr 3 is close woundv and normall i coy having its twolianges lland 12 horizontally and its `web 13 verticallyarranged.. The hoolr bolt8 is arranged with its head against the Aweb 13and the body of bolt close to the under side of the lower liange 11. Tohold up the t'ree end of the bolt I provide an angle clamp member 14;.having an arm 15 adapted lto Contact with the upper,` side of the lowerflange 11 anda second arm17 provided with a hole `18V for receiving thefree end of the bolt 8. I arrange the spring eye 7 just outside of thearm 17 of the angle clamp member14 and I secure the whole tightly uponthe channel member l bya nut v19 screwed into the threaded end of thebolt.

Between' the nut 19 and the eye 7 I preferably place avrsplitwasher 2Oof usual form tol prevent the nutlt) jarring loose. The strains to whichthe spring 3` and eye T are subjected aredownward and I placi` the eyeoutside oi the angle member whereby the downward strain is takendirectly by the angle member and lowertlange l1 ot'- the channel 1. n iThis construction also has another advan tage in` that `the strain onthe eye being away from the channel and the angle mem.- ber supportarranged ,betweenthe eye and the channel `member the angle member Aactsas a fulcrum and the strains consequently tend to force and hold thehooked end of the bolt upward against the channel member, in other wordstend to retain the bolt in op- It will be observed that the threaded endof the bolt is lnade eXtra long so that the device can be applied tochannel members of different sizes and then the eXtra length it any canbe cut 0E.

The strap 4; is preferably made of a single piece of suitable flexiblestrap material. I secure a buckle 2l to the end 6 of the strap bypassing the end 6 around abar 22 of the buckle and the end of the strapis secured to the body of the strap by rivet like fasteners 23 close tothe bar 22. The end of the strap then secured a second time to the bodyby rivet like fasteners .24 forming a space for receiving the end 25 ofthe spring 3. This end of the spring is bent transversely of the springwhere it connectswith the strap and the extreme end 26 of the spring isbent up at a right angle to prevent the strap slipping off.

lIhe buckle is of the pinch plate kind as differentiated from the tonguevariety and consequently I am enabled to adjust the length of the straploop accurately to fit the conditions and I do not have to weaken thestrap by making holes in As many modifications of my invention willreadily suggest themselves to one skilled in the art, I do .not limit orconfine my invention to the specific details of construction hereinshown and described.

I claim:

l. A rebound check comprising a strap adapted to pass beneath an axle,an extensiblespring connected at its lower end to the upper part of thestrap, the upper end of the spring formed into an eye, a hooked boltpassing through the eye, an angle member having a hole in one flange forreceiving said bolt, the other flange of the angle member adapted toengage over a frame part above the axle, the angle member arrangedbetween the spring; eye and the hooked end of the bolt and means fordrawing and holding the hooked end of the bolt and the angle memberclamped against and upon a frame member as and for the purposespecified.

2. In a rebound cheek of the kind described, an extensible spring, oneend of the spring formed into an eye, adapted to stand vertically, abolt passing through said eye1 an angle member having a hole in oneflange for receiving the bolt, the other flange adapted to extendparallel with the body of the bolt and toward the head of the bolt, theangle member arranged between the spring eye and the head of the bolt.

3. In a rebound check of the kind described, an extension spring, theupper end of the spring formed into a central eye adapted to standvertically, a bolt having a hooked head passing through the eye, anangle member having a hole in one fiange l'or receiving the bolt7 theother'flange oi" the angle member projecting toward the head of the boltand substantially parallel with the bolt, the spring eye arranged on thebolt, outside of the angle member and a nut on the bolt adapted to clampthe spring eye against the angle member, the angle member to and uponone edge of a' supporting member, and the booked head of the rboltagainst the opposite edge of the supporting member.

4. In a rebound check of' the kind described means for securing thedevice upon a supporting member having a horizontally extending flange,comprising` a bolt having a hooked head adapted to engage one edge ofthe supporting member and to extend beneath same, an angle member havinga hole in one flange to receive the bolt, the other [lange ofthe anglemember adapted to entend over the supporting member, a check springprovided on its upper end with an eye to receive the bolt and arrangedon the bolt against the outer side of the angle member and a nut on thebolt for clamping the eye against the angle member and the angle memberand hooked end of the bolt against the two edges of the supportingmember.

The combination with a frame member having a vertical web and ahorizontal flange at its lower edge, a clamp for securing a pull springdependent below said flange, comprising an angle member arranged withone leg in contact with the upper surface of said horizontal flange andthe other leg against the free edge of said liange, a threaded boltadapted to extend across beneath the flange and provided at one end witha head for contact with said web, the said dependent leg provided withan opening to receive the bolt and in position to hold the rbolt closeagainst the underside of said flange, a spring provided with an eye toreceive the bolt, the eye arranged on the bolt and against theouter-'surface of said dependent leg and a nut on the bolt for tightlyclamping the several parts together.
